Problems solved by technology

The exterior wall system directly fixes the OSB (Ou Song board) board on the cold-formed thin-walled steel column with screws. The disadvantage of the OSB board is that its mechanical properties are poor; the overlap between the OSB board and the board is not tight, and the waterproof performance is poor.
The connection between the insulation board and the cold-formed thin-walled steel column is added, the construction is complicated, and the quality is not easy to guarantee

Abstract

The invention relates to an outer wall system based on a polyurethane sandwiched steel plate, comprising a gypsum plate, a steel stand column, glass fiber cotton, the polyurethane sandwiched steel plate and an outer decoration layer, wherein the gypsum plate and the steel stand column are connected into a whole with the polyurethane sandwiched steel plate respectively, the glass fiber cotton is arranged between the gypsum plate and the polyurethane sandwiched steel plate, and the outer decoration layer is arranged on the outer surface of the polyurethane sandwiched steel plate. Compared with the prior art, the outer wall system has the advantages of good waterproof performance, good thermal insulation effect, high fastness and good convenience in installation and the like.

Description

technical field [0001] The invention relates to a wall system, in particular to an exterior wall system based on polyurethane sandwich steel plates. Background technique [0002] The traditional cold-formed thin-walled steel exterior wall system consists of gypsum board a, cold-formed thin-walled steel column b, glass fiber cotton c, OSB board d, moisture-proof paper e, thermal insulation board f, and outer decorative layer g, see figure 1 . The exterior wall system directly fixes the OSB (Ou Song board) board to the cold-formed thin-walled steel column with screws. The disadvantage of the OSB board is that its mechanical properties are poor; the overlap between the OSB board and the board is not tight, and the waterproof performance is poor. The connection work between the insulation board and the cold-formed thin-walled steel column is added, the construction is complicated, and the quality is not easy to guarantee. Contents of the invention [0003] The object of the ...
